Hands-On Serverless Computing with Google Cloud

By: Richard Rose

Overview of this book

Google Cloud's serverless platform allows organizations to scale fully managed solutions without worrying about the underlying infrastructure. With this book, you will learn how to design, develop, and deploy full stack serverless apps on Google Cloud. The book starts with a quick overview of the Google Cloud console, its features, user interface (UI), and capabilities. After getting to grips with the Google Cloud interface and its features, you will explore the core aspects of serverless products such as Cloud Run, Cloud Functions and App Engine. You will also learn essential features such as version control, containerization, and identity and access management with the help of real-world use cases. Later, you will understand how to incorporate continuous integration and continuous deployment (CI/CD) techniques for serverless applications. Toward the concluding chapters, you will get to grips with how key technologies such as Knative enable Cloud Run to be hosted on multiple platforms including Kubernetes and VMware. By the end of this book, you will have become proficient in confidently developing, managing, and deploying containerized applications on Google Cloud.

Exploring Cloud Functions and Google APIs

In this example, we will build an application that will use Cloud Pub/Sub to provide resilient access to a document. Earlier, we introduced our new friend, Google Cloud Pub. Now we will get to see how we can utilize this feature as part of a simple solution.

Our application will create a time-constrained link to a text file, which can only be accessed by an authenticated source. This type of functionality is actually an everyday use case for transferring data securely across the internet.

General architecture

To create a signed URL, we will need an existing file that has been uploaded to a storage bucket. For the sake of this example, we will take the following approach in terms of...
